Adding shelves above bed

Wondering who has added single shelves across front above bed?  What did you use for anchors, and into what bracing? Just wondering of process. Wanted something to store ebags, etc.  thanks. Tom

Thanks

Many thanks to Vann for his inspiration!!  I was able to nearly duplicate his method of creating a shelf at the foot of the bed.  For the shelf I used left over wainscoting plywood, corner trim molding and for support directly under the shelf a split closet rod.  I fashioned for wall supports using some wood I had and attached at the endwall using screws and construction adhesive.  I attached the side wall supports to the wall where the aluminum frame is located next to the window and wardrobe.  In addition to this I moved the TV (another inspiration from Vann) down since it really is at a odd height to be enjoyable  also  it was in the way of the shelf.  I added support inside the wardrobe to carry the load of the TV and the shelf support.  A bit of calk and touchup paint should complete it.  A great space saver mod!

Just getting our 189 which is why I’m wondering if the studs at curved end over bed and the wall studs are different?  Aluminum vs wood?  How to locate. Best type/length screws to use. Thanks 

Rather than a shelf I decided to make a cabinet to hold the stored clothing over the bed in our 179.  This picture only shows 2 of the 3 cabinet doors and the cabinet goes the entire width of the trailer over the bed.  It has preformed well.  Hope this gives some more ideas.
